Kerk:
I haven't done it, but I've seen it done on a dockmates Waquiez 40. The panel is mounted on swivel clamps on the aft support bar. The bimini did have to be cut to allow access for the clamps. When he folds the bimini up, the swivels allow the panel to lay flat against the backstay. (Picture the panel facing aft.) He actually had a new piece of canvass cut so he could cover both the panel and the folded bimini, but he hardly uses it. He normally leaves the bimini unfurled and the panel at the optimum angle.
